For example:<\/p>\n<pre><code>try:\n    number = int(input(\"Enter a number: \"))\nexcept ValueError:\n    print(\"That's not a valid number!\")<\/code><\/pre>\n<p>You can catch multiple exception types by listing them in a tuple or using separate <code>except<\/code> clauses.<\/p>\n<h2>Adding Finally and Else<\/h2>\n<p>The <code>finally<\/code> block always runs, whether an exception occurred or not \u2013 perfect for cleanup (closing files, releasing resources). The <code>else<\/code> block runs only if no exception was raised, letting you separate success logic from error handling.<\/p>\n<pre><code>try:\n    file = open(\"data.txt\")\nexcept FileNotFoundError:\n    print(\"File missing.\")\nelse:\n    print(file.read())\nfinally:\n    file.close()<\/code><\/pre>\n<h2>Best Practices for Robust Code<\/h2>\n<ul>\n<li>Catch specific exceptions rather than a bare <code>except:<\/code> to avoid hiding bugs.<\/li>\n<li>Avoid swallowing exceptions silently; log or re\u2011raise when appropriate.<\/li>\n<li>Use <code>raise<\/code> to trigger your own custom exceptions for domain\u2011specific errors.<\/li>\n<\/ul>\n<p>Mastering error handling in Python leads to more predictable, maintainable, and user\u2011friendly programs. Start small, test your edge cases, and let try\u2011except become second nature.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Python Error Handling: A Practical Guide to Try, Except, and Finally Errors are inevitable in Python, but handling them gracefully makes your code robust.
